Sony MDR-PQ4 “Qlasp” Ear Clip Headphones (Pink)

The Sony MDR-PQ4 Qlasp are ultra-light in-ear earbuds with a clever ear-clip design that “clasps” the lower ear to stay put. They’re a nice fit for students who have trouble keeping standard earbuds in place, while still delivering clear stereo sound from compact 9 mm drivers.

Key features for education

• Ear-clip “Qlasp” fit helps prevent earbuds from slipping out during class movement or active learning.
• Hybrid silicone tips add comfort and a more secure seal for clearer speech and media.
• Cord slider keeps cables tidy and reduces tangles in student bins or carts.
• Lightweight design makes them easy to store and distribute for shared sets.
• Balanced stereo sound supports lessons, videos, and learning apps.

Compatibility and connection

These earbuds use a standard 3.5 mm stereo plug and work with most Chromebooks, laptops, tablets, and desktops that include a headphone jack. For USB-C-only devices, a USB-C to 3.5 mm audio adapter may be required if permitted by district IT.

Best use cases

• Everyday classroom listening (videos, lessons, apps)
• Students who need a more secure earbud fit
• Mobile learning and take-home kits
• Libraries or media centers where compact earbuds are preferred

Classroom notes

• No microphone: This is a listening-only model. If students need to record speech or join video calls, choose an earbud/headset with mic.
• Open, low-profile style: Great portability; allows some ambient sound in, which can be helpful for supervision.
• Tip sizing: Multiple ear tip sizes help fit a range of student ages.
